C6320

warning C6320: exception-filter expression is the constant EXCEPTION_EXECUTE_HANDLER. This may mask exceptions that were not intended to be handled

This warning indicates the side effect of using EXCEPTION_EXECUTE_HANDLER constant in __except block. In this case, the statement in the __except block will always execute to handle the exception, including exceptions you did not want to handle in a particular function. It is recommended that you check the exception before handling it.
